Pros
Pro Six simultaneous devices allowed
Users can use the same VPN account on six devices at the same time. Clients who have a lot of computers and smart-phones at home can set up their router with VPN which will use only 1 device slot and will provide VPN connection to all connected devices.
Cons
Con P2P traffic only allowed on certain servers
If you transmit any kind of BitTorrent P2P traffic on certain servers, all of your active connections will be automatically terminated and you will be transferred onto a different server where file-sharing traffic is "allowed". This is not mentioned in the Terms of Service, and is only vaguely mentioned in the FAQ: "Yes, we allow P2P traffic on certain servers. The server list that allows it: Romania, Russia, Sweden, Latvia, Luxembourg, Netherlands, Canada."
This suggests that NordVPN might do live deep packet inspection on your VPN traffic in order to determine if it's BitTorrent traffic or not.
